Abstract

Vanne assurant le pré-remplissage et la vidange rapide d'un vérin hydraulique. Le corps 1 étant fixé sur le vérin 30, au début de la course descendante rapide de celui-ci 2 s'ouvre pour permettre à l'huile de la bâche 20 d'affluer dans le cylindre 30.2 se referme pendant le travail sous haute pression dans 30. Lors du retour le distributeur 14 fait entrer en jeu le clapet 11 pour assurer d'abord la décompression progressive à travers 13. Puis 4 se déplace vers la droite pour tirer 2 et permettre l'écoulement libre vers la bâche 20. Application aux presses hydrauliques.
